Patented Dec. 31,1912.

application filed January 9, 1912. Serial No. 670,145.

I To all whom. it may concern: 1

Be it known that 111,,Anrrrun T. Burr-WEN, a citizen of the UnitedStates, residing at Topeka, in the county of Shawnee and State ofKansas, have invented CPl11ll1 new and useful improvements in-Carbureters, of which the following is a specification.

My invention relates to 'earbureteraand my object to provide a simpleand ellicient apparatus of this character which may be employed'toatlvantage in supplying gaseous fuel to the motors of automobites, tothe end that the carburet'ers now in general. use for that purpose maybe dispensed with.

By employing my apparatus, an adequate amount of fuel-of uniformrichness is al ways insured, and'in order that the invention may befully understood, reference will now be made to the accompanyingdrawing, in which:

Figure 1 is a-sectional View of asupply tank provided with my apparatus.Fig. 2 is a perspective of a float, forming an important feature of theinvention. Fig. 3 1s a cross section of the at, on line HI- HI ofFig. 1. Fig. 4: is a perspective of a wick, a plurality of which areemployed in carrying out the invention.

1 designates a supply-tank for holding .gasolene or other hydrocarbonoil to be convertedinto gaseous fuel. Said tank is provided with aninlet 2,,throu gh which it may be supplied, said inlet beingnormallyclosed by a removable cap 3.

4- designates thefloat, forming one of the important features ot'theinvention. Said float embodies a receiving-chamber 5, a dischargechamber 6, two air-chambers 7 and a wick-chamber 8. Thereceiving-chamber 5 is located at one endof the float, and thedischarge-chamber 6, is located at the opposite end of said float, whilethe wick-chamher 8 extends throughout the length of the float betweenthe two air-chambers 7. The receiving-chamber 5 is provided at its upperside with a nipple 9, having a hose connction 10, which hose isconnected at its upper end to an inlet-pipe 11, extending through theadjacent end of tank 1, and provided with an air-receiving funnel 12,having a strainer 1.3 to intercept dust or 0ther','foreign matter whichmight otherwise entersaid funnel with the air; vThe inlet pipe 11 is,provided with a check-valve 14,

' adapted to open toward the hose 10 When the apparatus is in operation.The air entering the receiving-chamber o is ,permitted to flow outwardtherefrom into the wickchamber 8 through a horizontal row of inlet-ports15, in the vertical rear wall of said chambers. The discharge-chamber 6communicates with the wick-chamber 8 through a horizontal row of inletports 16, in the vertical front wall 913' said chamber 6. The upperportion of the discharge-chamber 6 is provided with a nipple 17, havinga hose-connection l8, communicating with an outlet-pipe. 19, leading tothe motor or other point oftu'se, not shown. -Back-pressure from theoutlet-'pipe 19 to the dischargechamber 6 is prevented by a check-valve20, communicating with said outlet-pipe. Outlet-pi e 19 is provideiifwith an air-intake 21, provi ed with a valve 22 to control the flow ofair therethrough.

'23 designates a plurality of wicks consisting of any suitable absorbentmaterial,

each wick being stretched on a suitable frame 24. side in thewick-chamber 8 as-shown in Figs. 1' and 2, and are supported in saidwick-chamber .bya pair of flanges 25, re-

movably secured to thebottoms of the air' the intake 21, the amount ofair being regulated by the valve 22, which in turn may be regulated froma point adjacent the seat of,

an automobile when the apparatus is installed on a vehicle of thatcharacter. The air-chambers 7 are, preferably, so proportioned as tosupport the,upper half of the float above the level of the oil in tank1, so that it will not obstruct the passage of the air through the upperportion of the wick Frames 24 are placed side by l chamber, and at thesame time, seal the air the, tank 1.

frompassing from said wick-chamber into Although the float is free tomove up and down with the level of the oil within tank connectionsbetween the inlet and the re- 1 '1, it fits the interior of said tanksufficiently changes as properly fall within the spiritand scope of theappended claims.

Having th'usdescribed my invention what I claim and desire ent, is:

1. In combination with a tank, a float therein composed of a pair ofspaced transverse receiving and discharging chambers 'located'atopposite ends of the tank and a pair of spaced longitudinal side airchambers that are connected to the ends of the receiving and dischargingchambers, flanges carried by the bottoms of the air chambers andextending inwardly. to project in the space between said air chambers,wick frames having their bottoms seating on said flanges and locatedbetween the inner side faces of the air chambers, the inner walls of thereceiving and discharging chambers being formed with openings, an airinletin the tank, an outlet, and flexible hose to secure by LettersPatopenings which face each other and are 10- cated intermediate thetops and bottoms of said inner wallsto provide a direct hori- Zontalpassage through the space defined by the float, which openings directlycommunicate with the space bet-weensaid chambers,

a series of wicks supported by the float and located in said space, aflexible pipe directly connected at one end to the receiving chamber andat its opposite end to the tank for supplying air to the interior of thereceiving chamber and a flexible pipe directly connected at one end tothe discharging chamber and at its opposite endto the tank forexhausting the fuel from the discharging chamber.

In testimony whereof I aflix my signature, in the presence of twowitnesses.
